Fwd: [ACTIVITY] w51
Hi, * Continued with comparison of eembc results for gcc4.4 and gcc 4.6 (FSF and Linaro). Collecting results for 4.6 with loop-unrolling turned off. * Working on a plotbench.py script that will use matplotlib for plotting the results. Right now the script plots the geomean value, for instance for eembc. I now try to make it plot all subtest as well. Then it should also show relative improvements instead of just the numbers, and then also sorted from best to worse. This script depends on Michaels script libtabulate.py for transforming the tabulated file back to python records. * Will be back January 9 /Regards Åsa ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain

Hi, OpenEmbedded-Core: * No response on the CSL patches I posted to the ml yet * khem says someone (other than me) needs to try them * Linaro binary toolchain * Runs on Oneiric-X86_64 after installing lsb-core (interpreter: /lib/ld-lsb.so.3) * The do_rootfs tasks fails with runtine dependecy issues when using the external-linaro-toolchain_arm-2011.11.bb recipe. When re-using my CSL 2011.03 recipe with the linaro toolchain the error doesn't show up - strange. * OE-Core build gets confused by the (arm-linux-gnueabi-)pkg-config of the external linaro toolchain. As a workaround I just renamed this script. * The qemuarm MACHINE configuration uses "-march=armv5te -mno-thumb" Since the linaro toolchain defaults to thumb and -mno-thumb has no effect some inline assemblies are failing (i.e. on the umull insn). GNU #47930 suggests using -marm instead -> OE-Core patch posted. * Got the core-image-minimal to build, but it doesn't run yet (I suspect some basic runtime dependencies like libc again) * The build of the sato image fails (seems libtool and/or C++ related - need to investigate) Regards Ken ___ linaro-toolchain mailing list linaro-toolchain@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-toolchain
[ACTIVITY] 2011-12-23 - and goodbye
== QEMU == * Wrote the context routines for Eglibc, including those that QEMU uses These pass all the context tests I could find, including QEMUs coroutine tests, and with them QEMU seems to boot OK. I've got a full eglibc test run going at the moment, but I don't think anything else uses them. I posted them with comments and a question to libc-ports; I'll try and chase follow ups. == String routines == * I posted the strchr and strlen routines to eglibc (libc-ports) * On strchr the question of whether it was worth using the longer version that's faster for longer strings (but slower for shorter strings) came up. I posted some stats, observations etc - and there is still a discussion on going about it. * For strlen, rth noted the same trick that I'd originally seen in newlib (and for which RichardS and Ramana had suggested) of a quicker end-of-string sequence using clz. I'd avoided this because I'd originally seen it in newlib and didn't want to copy it; but since 3 people have individually suggested it it would seem using. == Goodbye! == Thank you all for a fun & interesting year! I'm sure many of us will meet online again in the future.I'll try and follow my linaro.org address while it's still live to check for any replies to any patches/comments etc. Feel free to mail me at david...@uk.ibm.com (work) or d...@treblig.org (home); for Linaro people I've also added some more contact methods at: https://wiki.linaro.org/Internal/People/DaveGilbert/Contact Thanks again!
